HYDRCARBON-BURNER.

.the following to be afull, clear, and exact' description of theinvention, such as will enable others skilled in thenart to which itappertains to make and use-the same.

lllhis invention relates to improvements `inhydrocarbon burners andmore'particu- 'larly to such as are adaptable for use with stoves of thetype commonly known as oil stoves,-one object of the invention being vtoprovide simple and elcient wick limiting'.

means carried by the combustion chamber member ofuthe device, which willalso. operate to transmit the weight of the combustion chamber membertothe wick to force the latter down when the combustion chamber memberis moved from its elevated to its is a sectionalview of the device, withthe.

parts in their normal operative positions. Fig. 2 is a similar viewshowing the parts forming the combustion chamber in elevated position.Fig. 3 is a transverse sectional View7 on the line w-os of.1i`ig.'1.Fig. i is a transverse sectional view, on the line y-y of Fig., 2,.andFig. 5 is a detail view.

1-2 represent two concentric wick-tubes separated suiliciently to form awiclccham- .wiclechaniber being closed in any suitable manner. A nipple3 is secured to the outer wick-tube 1 for attachment to a. supply pipeand this nipple' communicates with the lower portion of thewick-chamber. rlhe upperrend ofthe outer wicktube is provided with anoutwardly projecting annular 'hanged which is depressed somewhat, ornring an annular rib 5 at the upper extremity Y of fthe tube 1. The innerwick-tube 2 is provided with a depressed inwardly profleeting flange 6(the inner edge of which `may be bent downwardly as at 7), and anannular lrib 8, kis thus formed at the upper Specification of LettersPatent.

extremity of said inner tube 2. A wick 9 is located within thewick-chamber between the tubes 1 and 2 and provided with a perforatedvmetal wick holder 10. A hollow. boss 11 is located on the outer tube 1and communicates with the wick chamber and from this boss, a tube 12projects in a diagonal direetion,-said tube 12 and boss 11 constitutingsuitable bearings for a shaft 13 I which carries a toothed wheel 14located within the boss 11 and adapted to mesh with perforations of thewick-holder for raising the wick when the shaft 13 is turned. A

suitable knob or wheel 15 is secured to the annular ribs adjacent to thewick, an]l charred-portions of the latter can be readily removed withoutbecoming lodged in ,the immediate vicinity of the wick and thus theburner can be easily kept clean.

. rlhe annular flanges at the upper ends of the wick-tubes 1 and 2constitute seats for the lower ends of spaced foraminated shells 1G and17 which are suitably spaced apart to form a combustion chamber 18between them. The shells 16 and 17 are surrounded by a casingv19 whichis spaced from the outer shell 17 and is open at its upper end,- thelower end oit said casing being provided with an inwardly projectingbottom flange 20 having a plurality of perforations 21. The upper end ofthe inner shell 16 may be provided with a fixed cap or head 22 havingsuitable perorations and the lower end of said inner shell may beprovided with a perfoi-ated cap 23. The shells 1G and 17 and the casing19 may be hel-d in proper relation to each other by means of transverserods 24:.which pass through them.

A spider 25 comprising a plurality of radial arms7 is lined within theinner wiektube 2 of the burner and constitutes' a part of .the raisingand loweringand locking. means for the foraminated shells and theirsurrounding' casing. A cylindrical portion 2G depends troni the innershell 1G or morev strictly speaking, from the lower cap 23 of said shelland. enters the cylindrical space formed by the inner wick tube 2 andsaid eylindrical portion 26 serves to assist in guiding the shells andtheir surrounding casing! in' their vertical movements. The lower endn'ular flanges at the upper ends of the Wicktubes 1 and 2 and the legs27 will be disposed between the arms of' the spider 25 but withoutactual contact 'with the latter. lfVhen the shells forming thecombustion chamber shall have been thus disposed, said shells with thecasing 1S) and the depending i Acylinder 2G can be turned so that one ofthe arms of the spider will enter the elongated slot 3], in one of thelegs 27 and the parts will then be locked against vertical movement. Bymaking-the slot 31 of appreciable length, theshel s can be partiallyrotated `back and'fortli,l until they shall have become accuratelyseated' upon the annular flanges ot the' wipli-tubes 1 and 2 and thusprevent any d /trimental air currents entering 1n close proximityto theupper end of the wick. The casing 19 is provided with a suitable knob orhandle 32 for manipulating said'casing and the shells 16-17 for raisingthe same above the wick, or for lowerlng them as will now be explained.

Assummg that the shells 16 and 17 are resting upon their seats on thewick-tubes 1 and 2 and it is desired to raise said shells,

Qthe operator will turn said shells and casing V and the beveled edges28 of the legs 27,

lriding on the arms of thelspider 25, will cause sald shells and casingto rise and when the seats 29 shall have become disposed upon 4the upperedges of said arms of the spider, the shells and casing will besupported in their raised positions above the wick.

The stops 30 at the lower ends of the legs 27 will engage the arms ofthe spider and prevent the combustion shells and easing from beingturned too far. After the wick shall have been lighted, the Operatorwill turn the combustion shells and veasing 1nthe reverse dlrection farenough to move the seats 29 off of the arms of the spider 25 and thenthe Weight of the parts will be sutlicieut to cause the combustionIshells to move downwardly upon their seats at the upper ends of thewick tubes and then by a further rotation of the combustion shells andcasing, the depending cylinder will be partly rot-ated and its L-shapedleg will be caused to coperate with one of the arms of the spider tolock said combustion shells and easing against upward movement.

In order t0 prevent the Wick from being raised too far within thecombustion chamber, I provide within the latter, near its lower end, aplurality of spaced limiting devices These limiting devices mayconveniently consist of a number of narrow may be disposed in more orless close.

proximity to the wick Without detracting from the etliciency of theflame.. Should it happen that the operator would raise the wick untilthe perforated holder thereof passes the toot-hed wheel of the Wickraising devices so that the turning of the shaft 13 in the reversedirection would not effect the lowering of the Wick, the weight of thecombustion shells and the casing transmitted to the upper end of thewick `through the medium of the spaced stops orflimiting devices 83,will cause the wick to be lpushed down far enough to insure theengagement or' the wick raising toothed wheel With the perforated wickholder.

While I have shown and described means for raising, lowering` lockingand propping the combustion chamber member of the device, I do notherein claim these devices speeiiically, the same constituting thesubject matter of my copending application Serial No. 718,936.

Various changes might be made in the details of construction and therelative arrangement of the parts without departing from the spirit ofmy invention or limiting its scope, and hence I do not wish to restrictmyself to the precise details herein set forth, except asparticularlyspecited in the claims.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is: A

l. In a hydrocarbonburner, the combination with a wick tube melnber, acombustion chamber comprising concentric foraminated shells adapted tolrest upon the wick tube member, and means for raising and lowering saidcombustion chamber member, of an ginnular series of fingers carried bythe combustion chamber member and vertically movable with the same, saidfingers disposed transversely in the lower portion of the combustionchamber across the path of the wick so as to constitute limiting meansfor the latter'.
